The concept above, originally posted on Behance, is nothing like the real Healthbook. Yesterday 9to5Mac gave the world its first look at what Apple’s currently in-development health and fitness tracking app really looks like. Apple decided to take cues from Passbook for the app’s UI design and a bold iOS 7 color palette comes along for the ride. What if it decided to go a different direction? The concept below imagines a card UI that borrows from the 3D Safari tab view and opts for almost entirely white UI, a stark contrast from what we know the real thing looks like.
